Have you ever heard about the Pantone system? We're not speaking about the color-matching system used by graphical designers but a system that is claimed to optimize combustion in engines and reduce pollution.The name of the system comes from Paul Pantone, an American who thought, "If 40 percent of the hydrocarbons that enter the motor are left unburnt, how can we help to achieve full combustion?".
The solution was rather simple: using the heat from the exhaust pipe to pre-heat the gas/air or diesel/air mixture before reaching the motor. Sometimes, even water vapor is added to further heat the mix. Applying some basic thermodynamics, the hotter the gas is, the more space it needs. Considering that the space available is the same, the mix that arrives is poorer in hydrocarbons and already hot, thus easier to burn.
A website offers results which look quite interesting. Follow the jump to read them. As always, take this with a little bit of precautions. It's good, however, to know that there's a way to go to improve current combustion engines until the best options arrive.

No pantone testing. Base results
Idle: CO = 4,5 % CO2 = 1.7%, ppm HC = 7000, O2 = 13%.
Medium revs: CO = 5.04 % CO2 = 1.9%, ppm HC = 8200, O2 = 13.7%.
Top revs: CO = 6.4 % CO2 = 3.6%, ppm HC = 3850, O2 = 11.4%.
Pantone installed
Idle: CO = 0.7 % CO2 = 4.6%, ppm HC = 88, O2 = 13.6%.
Medium revs: CO = 0.03 % CO2 = 6.4%, ppm HC = 95, O2 = 11.9%.
Optimum revs: CO = 0.06 % CO2 = 6.2%, ppm HC = 000, O2 = 12.2%.
Top revs: CO = 0.01 % CO2 = 6.2%, ppm HC = 000, O2 = 12.1%.
